Overview
FitCalc ("we", "us", or "our") operates fitcalc.health(the "Service"). This page describes what information is collected when you use the Service and how it's used. We take a privacy-first approach: we don't require accounts, sign-ups, or personal information to use any of our calculators.
Information You Provide to the Calculators
The values you enter into our calculators (weight, height, age, etc.) are processed entirely in your browser. This data is never sent to our servers, stored, or shared. When you close or refresh the page, that data is gone.
Information Collected Automatically
Like most websites, our servers and third-party analytics tools automatically collect certain technical information when you visit:
- IP address (used for regional analytics, not personally stored)
- Browser type and version
- Operating system
- Pages visited and time spent on each page
- Referring website (e.g., Google, Reddit)
Cookies and Tracking Technologies
FitCalc uses cookies and similar tracking technologies through third-party services. A cookie is a small file placed on your device to help operate or analyze the Service.
Google Analytics
We use Google Analytics 4 to understand how visitors use our site. Google Analytics uses cookies to collect anonymized usage data such as pages visited, session duration, traffic sources, and approximate geographic location. This helps us improve the Service. You can opt out using the Google Analytics Opt-out Browser Add-on.
Google AdSense
We may display advertisements through Google AdSense. Google, as a third-party vendor, uses cookies to serve ads on the Service. Google's use of the DART cookie enables it to serve ads to our users based on their visits to our sites and other sites on the Internet. Users may opt out of the use of the DART cookie by visiting the Google ad and content network privacy policy. You can also manage your ad personalization settings at adssettings.google.com.
Third-party vendors and cookies
Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites. These third-party vendors may use cookies and web beacons to collect information about your use of the Service.
How We Use the Information

- Understand which calculators and content are most useful
- Improve site performance and user experience
- Serve relevant advertising (through AdSense)
- Diagnose technical issues
Information Sharing
We do not sell, rent, or trade your personal information. Technical usage data is processed by our third-party service providers (Google), which operate under their own privacy policies.
Children's Privacy
FitCalc is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe your child has provided us with information, please contact us so we can delete it.
